Abstract: A mobile imaging system can include a camera system configured to capture images in a visible, a near-infrared, and an infrared light spectrum, a filter assembly including at least two optical filters, an illumination module activatable to emit light, and a computer system including processing circuitry configured to perform operations including control the camera system to collect multispectral imaging data of biological tissue associated with an injury or ailment of a patient and process the multispectral imaging data to assess the injury or ailment; a battery arranged to power the mobile imaging system, and a housing encompassing the processing circuitry and the battery.

Abstract: A method and system for specifically detecting perfectly matched probe-target hybrids by annealing a hairpin-based probe to a nucleic acid target under conditions favoring the formation of perfectly matched targets over mismatched targets, and electrochemically detecting the annealed probe. Sensitivity of detection can be enhanced by catalyzed reporter deposition of probe signal prior to electrochemical detection. Specificity can be enhanced by including hairpin-based competitor probes in the annealing step. The detection assay is particularly applicable to typing single nucleotide polymorphisms by DNA sandwich hybridization.
